To all whom t may concern:

Be it known that I, WILLIAM GRUs, Jr., a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oil-Cups, of which thefollowing isa specification. v

his invention relates to al device for attachment for admitting oil orinserting oil to a bearing or vinto anyplace in whichv a liquid is used,and although intended principally for use with oil it can of course havea more eneral application. The rincipal object o the invention is toproviso anew and improved form of oil cupl which is sim-y pleandinexpensive to construct and effective and eliicient operation. l

In the accompanying drawing, Figure 1 with a portion broken away of anoil vcup constructed in accordance with the principles of thisinvention; Fig. 2 isla sectlonal View taken on the'line "22 ofFig. 15\Fig. 3/is a sectional! view .taken on `the lmel 3 3 4shows the form ofa blank from which the of Fig. 2; Fig. 4

cap is made; Fig. 5 is a sectional view of the preferred constructionvof an oil cup/embodying this invention, and Fig. 6 is a'sectional viewtaken on the line 6 6- ofI Fig. 5.

In most of the oil cups lof the class towhich this invention belongs,that are in use at the present time, thereis some deficiency whichrenders them unt fory continuous service. Frequently the caps are hingedto the body of the oil cup or the cap is slldable relatively to the bodyuncovering an aper ture through which the spout of the oil can may beinserted. Or there is a slide or movable portion in connectionfwith thelside or top of the oil cap which when' moved un-A covers an aperture forthe insertion of an oil can spout. All of these constructions areunsatisfactory for the/reason that if the cap -is hinged the connectionis usually of suc a iimsy nature that olthe cap,

the least jp11/ll will `tear and .in the slidable or movable partconstructions the least dentor inaccurac will make it impossible toslide the mova le parts, thereby rendering it impossible too of oil. Isprings are used they frequently do not seat the cap or cover properlywhich will ermlt the admission of dirtad grit, there y decreasing theeiii'ciency ofthe oil cup, if not actually clogging it. In the f selfclosing, it is grasping the crimped edge en the oil cup .for theinsertion present construction these diiculties are overcome by having aspring which may be compressed aonsiderable amount, thus allowing thecap to be raised above the body ofthe oil cup to a considerable distancefor the insertion of oil. -A spring is provided which `tends toseat'lthe cap evenly and firmly so that there is very little opportunityfor dirt to get in'the cup, and being proof against inattention on thepart of the operator. f

Referring now more particularly to the drawing, an oiljcup body 8, asshown in Figs. 1, 2 and 3, is formed aty one end with a threadedportion"-9 adjacent;A which is a hexagonal portion l0 for screwing thebody into a threaded aperture. The other end of the body isentrely openwith the exception vof opposite tongues l1v which are bent inwardly a`short distance with extremities 12 bent into .the body 8. j lA c'overor .cap 13 is formed from a blank, as shown by Fig. comprising a roundedcentral portion 14 with oppositely extending arms 15. The arms are bentsubstantially at right angles to the plane of the -cap so that they maybe' inserted in the `body 8, as clearly shown in Fig. 3, the edge ofthecentral portion 14; being crimped around the edge'l, as shown in Fig. 3,to form a seat which rests against the open edge of the body 8. Theextremities 17 of the arms 15 are bent inwardly and then at rightangles, as shownv in Figs. 2 and 3, so that when the cap is applied* tothe body the bent extremities 17 and 1l are opposite each other.kBetween these, extremities a coil spring 18-is inserted which'is held inplace by tliebent extremities tending to hold' the ca over and closelyagainst the /open end o the body portion 8. The spring is worked inplace vwith the lcap partially raised and whenU/in .position there is notendency for it to become dislocated nor to bear vunevenly upon the cap.'Ihe cap is easilyAY raised for theI insertion of oil by 16 at anypoint', or at opposite points, as the edge of the cap protrudes beyondthe body 8.

In the preferred form, as shown by`Figs. 5 and 6, the body portion 19ofthe oil cup is vshown to be made of a tubular member which is reducedat one end forming the threaded portion 9 and an intermediate `headedportion 10. A cap 13;is made of a blanx similary to\that shown inFig. 4'and the rounded portion of thecap is strengthened by an insert 20 whichis crimped and held in place at the edgesfwhen the cap is formed.Instead of bending the extremities of the, arms 15 and forming tongueson the body portion of the cup in order` to hold the spring 18 in place,a pin 21 is attached adjacent the open end. of the body 19 andtheextremities 15 of the cap member are joined by a pin 22. As shown inFig. 6, this pin 22 is formed with flattened or upset portions 23adjacent the ends to prevent the arms 15 from moving inwardly, and theends of the j arms 15 are bent slightly as at 24 so that the heads 25 ofthe pin 22 will be'flush with the Aouter surface of the arms. This willfacilitate the insertion and operation of the cap in the body. y

One of the principal advantages gained bythis construction is that itcan be made `of thin tubular and sheet material by punch pressoperations. This makes the/construction simple, strong and inexpensive,and one that is not likely to get out of order. The cap is easily raisedfor the insertion of oil and is held strongly but evenly on the body ofthe oil cup. The coil spring is not easily displaced and leaves a largecentral opening for the admission of oil, at the same time permittingthe egress of air at the time of g. What I claim is:

l. In an oil cup, a receptacle` a non-y tilting ycover for thereceptacle having yparallel arms extending into and closely.

adjacent the sides ofthe receptacle, and a spring inserted within thereceptacle and between the arms tending vto hold the cover on thereceptacle.

2. Irfan oil cup, the combination with a receptacle open at one end, anda cover therefor having .integral guiding arms which extend parallel toeach other within and adjacent the walls of the receptacle to preventthe vcover from tilting.

3. In an oil cup, a receptacle open at one end, al cover thereforconstructed lof a single piece of material having parallel arms thatextend from opposite sides of the cover and downwardly into and alongthe sides' of thel receptacle to prevent tilting, and means for engagingthe arms yieldingly holding the cover in place.4

4. In'an oilcup, the combinationwith a receptacle open at one end, of acover therefor comprising a flat piece of sheet material having anenlarged central portion and oppositely extending arms, theedges of thecentral portionbeing crimped to t over -the end of the receptacle withthe arms extending within the receptacle, and means to hold the lcoveron the receptacle.

5. In an oil cup, anopen-ended receptacle, a .coverr tting over thefopen end. with vend of the spring, and means at the en the cover'andprevent it from tilting, and` a sprlng for holding the cover in place.F

7. In an oil cup, a tubular member forming a lreceptacle and reduced andthreaded at one end with Aan intermediate angular portion, a non-tiltingcover for the 'other end having integralarms forming a guide `slidablein and close to the wall of the member; and a spring for. holding theicover in place.y j i v 8. In an oil cup, the combination with areceptacle open at one end, a cover for the open `end having integralarms /extending close to the wall within the receptacle to preventtilting, means attached to the receptacle adjacent its open end for-engagin on;

o the said arms for engaging .the other` end of the spring.

9. In an 011 cup, the combination with an open ended receptacle, of/a'cover therefor formed of a iat piece of sheet material with a largecentral portion and oppositely extending arms, the -central portionbeing crimped at the edges to bend the arms to tacle, a reinforcementfor the rounded por-` tlon of the cover, and means for yieldingly`holding the cover on thereceptacle.

' 11. In an oil cup, a. receptacle having an open end, a cover thereforhaving arms extending into the receptacle, on opposite sides forming a'guide to revent tilting, acoil spring" insertible within the.receptacle,

`means at the ends of the arms to engage one end of the coil spring, andmeans adjacent the open end of the receptacle extending transversely ofthe arms for engaging the other end of the spring. i

12. vIn an/'oil cup, a vreceptacle formed a of. tubular material/reducedand threaded at vone `end and open at the other, a cap4 for theA openend composed of sheet material lwith integral' arms extending into theopen end of the/receptacle adjacent the sides thereof to preventtilting, a reinforcement for the cap, a pin connecting the extremitiesmemset of the arms, a member extending tran@a Versely of the arms andattached to the re ceptaole at the open end, and a coil springinterposed between said member and the pin at the extremities of saidarms which tends to hold the cover on the receptacle.

13. In an oil cup, an open ended receptacle; a cover therefor formed ofa fiat piece of sheet material with a central portion extending over thetop of the receptacle and integral arms bent inwardly from the edge ofthe cover and insertible within the receptacle forming a guide for thecover to revent tilting; and ineens for yieldngly oldin the cover inplace.
